Details
This policy setting allows you to filter a list of digital certificates for signing Excel, PowerPoint, and Word documents, based on the Key Usage field. The Key Usage field in a certificate is used to represent a series of basic constraints about the broad types of operations that can be performed with the certificate. Key usage filtering allows you to filter the list of installed certificates that can be used for signing documents. The filtered list will appear when users attempt to select a certificate for digitally signing a document.
Solution
Set the policy value for User Configuration -> Administrative Templates -> Microsoft Office 2010 -> Signing ‘Key Usage Filtering’ to ‘Enabled’.
